Rich plant sources of thiamine (vitamin B1) are sunflower seeds, peanuts, and soybeans. Good sources are whole wheat and nuts. It should be noted that thiamine is extremely sensitive to alcohol and sulfites. In the presence of either, thiamine is destroyed or made useless. Thiamine is also destroyed by anti-thiamine factor in uncooked freshwater fish, shellfish, and tea. There is no known toxicity due to thiamine.
